METALLIC MEASURILNGfVESSEL.

SPECIFICATION forming' part of Letters Patent No. 370,681, datedSeptember 27, 1887.

' Application led March 8, 1887. Serial No. 230,118. (No model.)

To all whom it may concern: Be it known that we, BENJAMIN F. CALD WELLand WILLIAM F. PETERSON, citizens of the United States, residing atVv'heeling, in the the county of Ohio and State of West Virginia, haveinvented new and useful Improvements in Metallic Measuring-Vessels, ofwhich the following is a specification.

' The object of our invention is to provide a novel and improvedconstruction for the cylindrical bodies of sheet-metalmeasuring-vessels, whereby the strength, finish, and durability of themeasure are greatly improved Without increasing the expense ofmanufacture.

The invention consists of the several novel features of construction andcombination of parts, hereinafter fully set forth, and definitelypointed out in the claims following this description.

Referring to the accompanying drawings, Figure l is a perspectiveview'of a metallic sheet of the kind used in the manufacture of measuresafter receiving its marginal corrugations. Fig. 2 is a similar viewshowing'the sheet after its corrugated or beaded portions are foldedover upon the body portion. Fig. 3 is a perspective showing the vesselformed of the metallic sheet and a bottom inserted'. Fig. 4 is a partialsection showing themanner of inserting and fastening the bottom.

In the said drawings, the referencenumeral l designates a dat sheet ofmetal of the kind suitable for the manufacture of metallic measuring-vessels. Said sheet may be of any desired length and of awidthsomewhat greater than the depth'of the linished vessel. In the marginalportions of said sheet are formed corrugations or beads 2 2f", producedby suitable rolls, vthe convex faces of said ribs projecting from thatface of the flat sheet which forms the interior of the finishedmeasure.V

The corrugated portions are then folded over and down upon the body ormain portion of the plate, as shown in Fig. 2, the line of fold be- Inorder to strengthen and support the corrugations or beads, we inserttherein, while the sheet is in the form shown in Fig. 2, strips 3,formed of wood or other material, and of such shape as to fill the spacebetween the Wall of the bead and the body of the plate. When the sheetis bent into cylindrical form, these filling-strips bend with it andform loops, which notonlyimpartgreatadditional strength to the vessel,but support the beads and prevent dinting.

The bottom 4 is insertedafter the cylindrical body is formed. It is ofwood or other suitable material and has a diameter which fits themeasure. A circumferential groove, 5, is formed in its edge, and afterit has been inserted and adjusted at the proper point the met-al of thebody part just above the beaded portion is swaged inward to fill thegroove.

If rolls are employed to bend the plate into cylindrical form, they aregrooved to receive the beads 2 and 2n and prevent the latter from beingattened.

By our invention we provide a measure the body of which is made of asingle piece of metal having a perfectly-smooth inner surface, with thecorrugations or beads on the outside only, and provided with a solidsupport with in such beads.

Having thus described our invention, what we claim ism I. The metallicmeasuring-vessel consisting of the cylindrical body l, having in itsmargins the corrugations or beads 2 2f, bent over and down upon the bodyportion, substantially as described.

2. The metallic measuring-vessel consisting of sheet I, having itsmargins provided with beads or corrugations 2 and 2f, bent over and downupon the bodyportion, the tillingstrips 3 in said beads, and the bottom4, substantially as described.

In testimony whereof we affix our signatures in presence of twoWitnesses.
